Until recently, finding mobile phone RS was a
very difficult task, as it was recorded the details of holders of prepaid. But
from 2011 onwards with the relevant legislation had even numbers on prepaid
holders to disclose their data to the corresponding prepaid, to put in place
their numbers. In this way they wanted to minimize the issues of malicious
calls from phones hidden that even with intervention prosecutor could not
establish the elements of the owner of the number.
